The identification of structural chromosomal aberrations can provide insight into causative relationships with complex phenotypes—including intellectual disability, developmental delay, and congenital anomalies. Chromosomal microarrays are powerful tools for detecting many types of structural variation.
Chromosomal microarray analysis leverages the investigative power of single nucleotide polymorphism (SNP) genotypes to detect imbalances in copy number and allelic homozygosity, which are commonly associated with genetic constitutional disorders.

Chromosomal microarrays can detect variations that may be missed by other technologies. Traditional cytogenetic methods for the detection of dosage anomalies (copy number imbalances) are unable to assess allelic homozygosity and therefore miss potentially significant findings.
Unlike oligo arrays, which can only identify copy number changes, SNP chromosomal microarrays can identify copy neutral changes, such as uniparental disomy (UPD), and loss of heterozygosity.
Ease of use and high-quality data support a smooth transition from oligo arrays to chromosomal microarrays.
